There are four general wing shapes that are common in birds: Passive soaring, active soaring, elliptical wings, and high-speed wings. Muscles are attached to the base of each feather, which allows the bird to move them as needed. With longer wings, the speed is faster and less effort is exerted in flapping. In terms of a side-by-side flight motion or a roll, the avians allow one wing to gain more lift compared to the other. Freshwater butterflyfish are found in slow-moving rivers and streams in Africa.
